Abstract
A cross-connect bit rate of 156 Mb/s was achieved without loss of a bit by the duplex transmitter using two DBR lasers and an optical LiNbO/sub 3/ switch with a switching speed of 4 GHz. The bit-error-free operation was experimentally verified by observing eye patterns. The proposed optical cross-connect scheme supports cross-connect bit rates up to 2 Gb/s if a 4-Gb/s switching device is employed. Only widely tunable lasers are needed to construct the optical cross-connect system utilizing the duplex transmitter, and the stringent requirements of frequency switching speed for lasers can be eliminated.<>Keywords
